Letters Patent No.` 88,907, dated A11/ril 13, 1869.

mPROvlEilidENT-IN SASH-STOP AND LOCK The Schedule referred to in theseLetters Patent and making To all whom 'it may concern:

Be it known that I, RnNssELAER RnYNoLDs, of Stockport, in the county ofColumbia, and State of New York, have invented a new and improved Sash-Stop and Lock; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification.

The object of this invention is to provide for the retention of slidingwindow sashes at any desirable height when raised, and for. the lockingof the same when down; and

The invention consists in a combined sliding wedge and falling tumbler,constructed and arranged for operating within the stile of awindow-sash, vand acting against the jamb, or inner surface'of thewindow-casing, whereby the sash may he retained at any desirable height,by the action of the apparatus as a wedge when the sash is raised, andsecurely locked by the actionof the same as a tumbler whenthe sash isdown. v

Figure 1 represents a side view of a sash and its casing provided withmy improved stop and lock, and

Figure 2 represents the apparatus removed from the sash, and furnishedwith a different means of operating the same by hand.

Similar letters of reference indicate corresponding parts in bothfigures.

' C is a wedge, of an upward-tapering or inclined form, constructed ofcast-iron, 0r other material, and `vertically arranged within acorrespondingly tapering or inclined excavation or mortise, c, cut intothe outer edge of the lower-portion of one of the stiles f, of the sashA. This wedge C is constructed tapering, or inclined upon its innerside," while its outer side remains straight i and even with the outeredge of the stile, but is so.

fitted within the correspondingly tapering or inclined mortise c, thatan upward sliding of the said wedge within the-said mortise produces anoutward lateral movement of the wedge, thereby causing its straight orperpendicular surface to project beyond the edge of the stile f, for apurpose hereinafter explained.

The said wedge C has provided upon its inner side, and near its lowerextremity, a horizontal arm, b, which passes through the stile f, bymeans of a horizontal opening, o, near the lower extremity of theexcavation c.

This arm b projects suiiciently. beyond the inner sash. The wedge beingthus part of the :me

surface of the stile f for convenient manipulation of the same inoperating th'e said wedge.

This wedge G also has provided upon the inner side of its lowerextremity, a downward projection, d, upon which the said wedge C restswhen not sustaining the supported upon its inner corner, its cen-tre ofgravity-is thrown outside of or beyond the point of support, which givesthe said wedge C a tumbler-like inclination to tilt over, and turningupon the projection d, as a pivot, to fall out of the mortise c, but isretained therein by the inner surface of the casing B, against which itrests.

q is an inverted notch, cut upon the inner surface of thecasing B, at apoint opposite the location occupied by the wedge O, when the sash isdown. When the sash is' brought to its lowest position, the said wedge Cacting as a tumbler, falls by its own gravity into the notch g, andlocks the sash.

When it is desired to open the window, the sash A is unlocked, bypressing down the lever b, which causes the wedge or tumbler C to turnupon the projection d as a fulcrum, thereby withdrawing the point of thesaid wedge, or tumbler O out of the notch g, when the sash may be easilyraised.

When it is desired to retain the sashin a raised position, the wedge Cis forced upward, by pressing upon the under side of the lever b, whichengages the sides of the wedge C more closely with Athe adjacentsurfaces of the stile f and casing B, thereby preventing the downwardsliding of the sash. The same result is produced by retaining, orholding rm the arm of the wedge O, and releasing the sash, which, bydropping, securely fastens itself by sliding against the wedge.

Instead of the arm b, the apparatus may be furnished with a headed pinor bolt, on, passing through a slotted opening in the front sidelf thestile f, and screwedinto the wedge C at a point thereon most convenientfor operating the same, as illustrated inl iig. 2.

What is here claimed, and desired to have secured by Letters Patent, isiThe :wedge-shaped sash-stop C, constructed with a projection, al, on theinner edge of its but end, whereby it is made to lock automatically whenthe .sash is closed, substantially as shown and described.
